Cerebrospinal fluid (CSF) is a clear, colorless liquid found in your brain and spinal cord. The

brain and spinal cord make up your central nervous system. Your central nervous system

controls and coordinates everything you do including, muscle movement, organ function,

and even complex thinking and planning. CSF helps protect this system by acting like a

cushion against sudden impact or injury to the brain or spinal cord. CSF also removes waste

products from the brain and helps your central nervous system work properly.
